UBW2A331MHD

The UBW2A331MHD is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 330 µF and a rated voltage of 100 V. Engineered for high-temperature endurance, this part is specified for operation from -55°C to +135°C and a rated life of 3000 hours at 135°C.

Designed for applications that require compact energy storage with robust ripple handling and long-term reliability, the UBW2A331MHD combines a compact φ16 × 30.5 mm can, radial lead form factor and automotive-grade qualification (AEC-Q200).

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Endurance — Rated for continuous operation from -55°C to +135°C with a 3000 hour endurance specification at 135°C.
• Automotive Qualification — AEC‑Q200 rating for suitability in automotive electronics environments.
• Ripple Current Handling — Low-frequency ripple current of 1.199 A (120 Hz) and high-frequency ripple current of 1.79 A (10 kHz) to support power filtering and decoupling under ripple loading.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) of 0.08 at 20°C, 120 Hz (for 100 V rating), and a measured leakage current of 990 µA.
• Low Impedance — Specified impedance of 79 mΩ to aid transient response and reduce voltage drop under load.
• Radial Can Package — φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm), radial lead mounting and bulk/bag packing options for production assembly.

Typical Applications

• Automotive Electronics — Suited for automotive electronic modules and systems that require high-temperature operation and long-life capacitors.
• High‑Temperature Power Systems — Applicable where capacitor endurance at elevated temperatures (up to +135°C) is required for sustained performance.
• Power Filtering and Decoupling — Used in designs that need 330 µF energy storage with rated voltage of 100 V and defined ripple handling at multiple frequencies.

Unique Advantages

• Extended high-temperature life: 3000 hours at 135°C provides predictable long-term performance in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronic systems that demand component-level qualification.
• High voltage capability: 100 V rating enables use in higher-voltage power rails and intermediate bus applications.
• Robust ripple handling: Specified ripple currents of 1.199 A (120 Hz) and 1.79 A (10 kHz) allow reliable filtering across low and high frequency domains.
• Compact radial footprint: φ16 × 30.5 mm can and 7.5 mm lead spacing deliver a space-efficient solution for through-hole assemblies.
• Verified electrical characteristics: Low impedance (79 mΩ) and low loss (tan δ = 0.08 at 120 Hz, 20°C) support stable performance under load.
